Just saw this one on AVweb:

Wow, someone was having a bad day at the office...

The obvious tower mistake is one thing, but I would also question the
judgement of the PIC of the second aircraft cleared... He really
should have been the one to catch the controllers mistake...

Granted, thats my own damn opinion and nothing else, I obviously don't
know enough to make a real judgement here
